A self-taught Magus and an avid fantasy reader ends up inside the Tower of God with Mordred's power and with Mordred's soul inside his Ignition Weapon as a result of his wish to the Holy Grail.
...
Summary:
The Main Character participated in a Holy Grail War and ended up being the final winner thanks to wit and luck, but at the cost of his Servant Mordred. As a result of his wish to the Holy Grail, he gained various powers similar to those of his Servant, his dead Servant Mordred was restored and took refuge inside his sword, and the two ended up inside the world of the Tower of God.

Over time, the MC discovers that the Tower is exactly a place where he can fulfill his various desires and wishes as promised, growing more powerful and achieving more than just a single wish could grant him.
...
It is mainly a Tower of God story. The only aspect from Fate verse is the MC and his abilities. The goal for the Main Character, initially, is to grow his powers and live an interesting life in the new world.

PS: Bam plays a very small role in this story, even though he's initially introduced.

PS2: Mordred is not a romantic interest. This is not her character. She is MC's platonic female friend and partner/Ignition Weapon for the majority of the story, since the base of her character design is a child seeking attention.

The other girls from TOG are the heroines, and mainly Endorsi.
Hwa Ryun also gets a lot of attention, but because of the nature of her relationship with the MC, she keeps her distance.
